SPECIFICATION forming part of Letters Patent No. 390.872. dated October9, 1888.

Serial No. 267.727. (No mmlel.)

To LZZ whom, it may concern.' A

Be it known that l, TARGE G. MANDT, a citizen of the United States, anda resident of Stoughton, in the county of Dane and State of Wisconsin,have invented certain new and useful Improvements in Running- Gears forVehicles; and I do hereby declare that the following is a full,clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification, and in which- Figure l is a perspective view of the underside of my improved runninggear for vehicles complete. Fig. 2 is aperspective detail view of one of the houndplates, showing the peculiarshoe whereby it is attached to the axles.

the clip on thc front axle, and Fig. 4 is a similar section through theclip on the rear axle.

Like letters of reference denote corresponding parts in the severalfigures.

My invention has relation to the runninggear of vehicles; and itconsists in the detail, construction, and combination of parts of arunning-gear, made ot'iron or steel, and adapted to be used incombination with my iniproved compound reach and tongue, which saidimprovements form the subject of two separate applications for patentsof even ldate herewith.

In the accompanying two sheets of drawings, the letter A denotes thereach, which is preferably, though not necessarily,constructed asdescribed in my application for patent hereinbefore referred to.

B denotes the reach-coupling for adjusting the distance between thefront and hind axle, and this coupling is preferably, though notnecessarily, constructed as described by me in my Letters Patent No.194,160, bearing date of August 14, 187 7 The letters C and D denote,respectively, the front axle and the rear axle, which may be of anydesired construction, and E denotes the sand-bar.

F denotes the front bolster, and G the rear bolster, all of which may beof any desired construction.

The hounds H of the front axle are constructed of angle-iron or steel,in a single piece bent into.a horseshoe shape, as shown on the drawings,their forward ends, H', projecting in front of the axle, where they areconnected by means ofthe drawbolt I, upon which the tongue is hinged.The rearwardly-projecting part of the hounds bears against thefriction-roller J, journaled in the under side of the reach, and theopposite sides of the horseshoeshaped hounds are locked rmly in placebetween the axle and the sand-bar by means of the clips K, the underside of the sand-bar being recessed to accommodate the horizontal flangeof the hound, so that this flange shall be flush or even with the underside of the sand-bar. y

In order to tix the hound firmly upon the axle, I bolt or rivet uponthat part of the hound which comes immediately above the axle and is tobe secured thereto apeculiarlyshaped shoe, L, the shape and constructionof which are illustrated in Fig. 2 ofthe drawings, and also shown in itsapplication in Fig. 3. By reference to these figures it will be seenthat this shoe consists of a plate or casting having a fiat part orplate, M, which is bolted or riveted to the downwardly-proj ectiugflange of the hound iron, and another part or plate, N, projecting atright angles therefrom, so as to overlap the horizontal houndtlange, andthis projecting and overlapping part N is provided at opposite ends withdownwardly-projeeting anges u a, the length of the projection N betweensaid downwardly-projecting flan ges corresponding to the width of theaxle, so that when the hound-iron is placed in position upon the samethe dat part or plate N will rest against the upper side of the axle, inwhich position it is held in place by its downwardly-projecting Bauges nn, as will appear more clearly by reference to Fig. 3 of the drawings.The shoe having been placed in this position upon the axle, the oppositelegs of the clip O (see Fig. 4) are inserted through holes bored in thehorizontal flange of the hound-iron, so as to straddle the axle on0pposite sides in the usual manner, in which p0- sition the clip islocked in place,so as to firmly bind the sand-bar, hounds, and axles bymeans of the usual clip plate, P, and nuts Q Q. In order to furtherstrengthen these several parts and interlock them still more tirmly,Ifurther employ, at each end of the axle and over each ICO clip-plate, asteel brace, R, which is bolted to the under side of the horizontalflange of the hound-iron on opposite sides ofthe axle, after it has beenfirst bent over the under side of the axle, so as to clamp the clipplateagainst the axle, as shown in Fig. 4. Thus it will be seen that thisbrace R, of which there is one on each side, serves not only to raiseand stiften both the forwardly and rearwardly projecting parts ofthehound-iron,but also serves as an additional means for looking the clip Oand clip-plate P in position, so as to firmly nnitethe sand-bar,hound-iron, and axle. In this manner I obtain `the greatest possiblestrength, durability, and rigidity in the front part of the running-gearwithout unduly increasing the weight of the same or complicating itsparts.

The rear part of the running-gear, or that part which is attached to andforms a part of the rear axle,D, is constructed in subsi antially thesame manner, though of course the parts are cfa dilierent shape-lhat isto say, the angle-irons which i'orm the hounds are not in a singlepiece, as in the case of the front hounds, but are constructed of' twoseparate angle-shaped steel bars, (denoted by the letters S SJ theforward ends of which are connected by the clamping device or couplingB, while their diverging rear ends are provided with shoes L', theconstruction and arrangement of which are in all respects similar to theshoes L,wherehy the front hounds are fastened upon the front anxle. Therear axle and its bolster are locked together by means of clips E inprecisely the same manner as the front axle and sandbar; but the rearbraces, R', do not extend across the under side of the rear axle, butare cut oif behind the rearmost clip-nut, as will appear by reference toFigs l and 3 of the drawings. In other respects the construction,arrangement, and combination of the rear hounds, the rear bolster, andrear axle are in all respects the same as that which has been alreadydescribed in describing the con struction,arrangerneut,and combinationof the front hounds, sandbar, and front axle with their clips.

In order to further sti'ien and strengthen the running-gear, as awhole,at such points where additional stiffness may be required, I employ asystem of bracerods, T, the arrangement of which of course depends uponthe particular type of wagon manufactured. By the peculiar constructionand arrangement of the front and rear hounds and their combination withthe axles, clips, and clip-plates, as hereinbefore described, I producea running-gear which, while very light, (especially where steel isemployed in the manufacture ofthe hound-irons and braces, yet possessesi m mense strength and rigidity, and, as a consequence thereof', greatdurability. I employ no superfluous parts, but, it will be seen, makemostof the parts of my improved running-gear serve a twofold andsometimes a threefold purpose.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United Statesl. In a running-gear for vehicles,the combination of the following elements: the front axle, thehorseshoe-shaped hounds or houndirons, made of augleiron or steel, in asingle piece, the sandbar, the clips, and the braces bearing against theclip-plates and fastened to the under side of the hound-iron ou oppositesides of the axle, substantially as shown and set forth.

2. As an article of manufacture, 'the houndirons, made oi'angle-iron orsteel and provided with the shoes L, adapted to bear against andinterlock with the axle, substantially as shown and set forth.

3. The combination, in the running'gear of vehicles, of the axle, thehounds provided with the shoe L, and the clips, substantially as and forthe purpose shown and set forth.

4. The combination of the hind axle, the honndirons S S, constructed asdescribed, the shoes L', the clips, and the bolster, all construeted andcombined substantially as and for the purpose shown and set forth.

5. The combination of the hind axle, the houndirons, constructed asdescribed, the shoes fastened upon said irons, the clips, the bolster,and the braces R', all constructed and combined substantially as and forthe purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoat'iixed my signature in presence oi' two witnesses.

TARGE G. MANDT.
